Experimental Dynamics of Stressed, Strongly Correlated Magnetized Plasmas
Abstract
We study the control of the rotation of a laser-cooled ion crystal in a Penning trap by a rotating electric field perturbation. We show that application of a small torque produces sudden angular jumps or slips' of the crystal orientation spaced by intervals when the crystal is phase- locked or stuck' relative to the rotating perturbation. The distribution of angular slips is described by a power law, where the power-law exponent depends on the applied torque. We believe this system is driven by a constant force and that small perturbations or thermal effects trigger the slips.
